To` ALL WHoM 1T MAY conceals;

Be it known that LPORTER L. SWORD,of Adrian, in the county of Lenawee, and State of Michigan, have invented certain new and useful improvements in Brick Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, in which-- Figure 1 is a perspective view.

Figure 3 is a bottom view,'showing the mode of adjustably supporting the horizontal rodsA .Figure 4 is a section on the line :t fr.

Figure 5, a perspective view of the followers detached.

The same letters are employed in all 'the figures in the indication of thesame parts.

These improvements are intended to be applied in the construction of brick machines under they patent of myself and George S. Tiffany, assigner to myself, issued June 14, A. D. 1864, to the specification of which patent reference is here made for greater certainty in such matters as may relate to the description ofthe parts of the original machine.

The machine is driven by a pulley, A, on the shaft B, on which is placed also the bevel-pinion C, which drives the bevelled wheel C', and the pinion D, which drives the spur-wheel D on the shaft E, which carries the bevel-pinion F, driving the bevel-wl1eel F on the shaft G of the pug-mill G. The clay is fed from the pugmill through the bed-plate H, under the adjustable inclined plate H, into the mould-wlieel S. The operation of the pug-mill and mould-wheel is fully LXplained in the patent to which reference has been made, and it is not necessary to repeat theodcscription hcre,'a's my improvements are not applied thereto. Opposite and near to the end of the adjustable press-plate H is placed the knife, which is constructed in several parts. A plate, I, with a vertical ange is attached horizontally under` the bed-plate H by set-screws I2, and also by set-screws passing through slots in the vertical flange. A steel plate with a bevelled edge in front is fastened to this plate. By means ofthe sct-screws the knife may be vertically adjusted in relation to the mould-wheel as desired; and While the edge shears ott" the superfluous clay above the moulds the elongated surface placed above the moulds smooths theupper'surface ofthe brick, which is carried under and in contact with it as the mould-wheel revolves. The knife is intended to set immediately upon the surface of the 'Wheel S, and it is necessary that it should be adjustable, so that it may be accommodated to thc wheel, which is subject to variations in position. The space between the knife and plate H is only suicient to permit the' clay cut oil" to escape freely. In the original patenty above mentioned the .mould-wheel lis described as being sustained upon the ivhcel N, supported by the rods M from tlie bed-plate H. These rods held the outer ends of the shafts O, passing through the wheels N, the inner ends 4thereof being sustained upon a block-placed lul'iderneath the centre of the mould-wheel. While the outer ends of the` axles O were adjustable the inner ends were fixed. It is important that the wheels N should bc adjustable,'so that each may' beheld firmly at all times against the wheel S; and one of my improvements consists irl/the mode of suspending the wheels N,and also the Wheel Il, which actuatcs the followers K, as explained in thel said original patent.' The axles of all these wheels are respectively suspended by the rods M from thc bed-plate H at their outer ends. .The length of the rods M may be controlled by the nuts screwed on to the same above the bed-plate. The inner ends of the axles are suspended upon the collar Q, which is fastened by'a nut to the stationary shaft U. This collar yhas notches in its under side, in which the ends ofthe axles O are received, and supported respectively upon bolts Q', the length of which maybe regulated by nuts on the upper end projecting through the collar. By the means set forth the ends kof the axles O may be adjusted independently, so as to preserve the relation of the wheels Nte the mould-wheel. The ring P, placed above the rods O, has rounded recesses in its lower face to receive and brace said rods. This ring is the invention of Henry Aiken, and I do not claim it. He was also the inventor of the collar Q instead of the central block. My improvement in the latter case consists in making the attachment of the several rods O to the collar Q in such manner that the rods may he independently adjusted, both at their outer andtheir inner ends. The mouldwheel S has its driving gearing upon its periphery, and it is driven by the spur-pinionL R ont-lic lower end of the shaft of the bevel-wheel C. The shaft U is stationary, the wheel S turning around it. The remaining yrtions of the brick machine are constructed as described in said orignalpatent; and, as my improvements do not relate to :my-partthereof, it is not necessary to repeat the description thereof in thislspeeitication.

What I claim as my invention, and desire to secure by Letters Potent, s-

1. The adjustable knife, when constructed with a cutting edge set opposite to und so near the pr'essplnte H that there is merely room for the shaving of clay to rise between them, and having a cutting edge und elongated horizontal blade adjnstably atttaehed at both ends to and below the bed-plate H, and resting upon the revolving mould-Wheel AS, so as to perform the double function of cutting olf the superfluous cla-y and smoothing the upper surface of the brick, substantially us described.

- So suspending the rods O sustaining the yWheels N and L that they muy be independently adjusted at both ends, substantially as and for the purpose set forth.

3. The combination of the bed-plate H and stationary shaft U with the rods M and VO, wheels N and L,-

collar Q, bolts Q', und mould-wheel S, substantially as and for' the purpose setforth.

4. The arrangement in a. brick machine of a stationary shaft U, mould-wheel S, revolving around the shine, and having gearing upon its periphery, und the driving spur-pinion R, substantially us set forth.

' In testimony whereofl. liave'signed my name to this specification in the presence of two subscribing witnesses.
